--- title: "1.8 release notes" canonical_url: "https://www.nutrient.io/guides/web/release-notes/1-8/" md_url: "https://www.nutrient.io/guides/web/release-notes/1-8.md" last_updated: "2026-06-05T20:16:40.342Z" description: "Review Nutrient Web SDK 1.8 changes with new APIs, stability fixes, performance improvements, and recommendations for upgrading projects." --- We’re excited to announce Nutrient Web SDK 1.8, featuring enhanced accessibility, new AI-focused document APIs, and a range of stability and performance improvements. See the full details in the [changelog](https://www.nutrient.io/guides/web/changelog.md#1.8.0). ### Accessibility improvements This release brings significant improvements to accessibility across the SDK, ensuring a more inclusive experience for all users. Measurement tools and the measurement annotation toolbar are now more accessible and customizable, making it easier for users to interact with documents. Widget annotations in Form Creator and Form Designer modes now offer enhanced keyboard accessibility, enabling smoother navigation and interaction without relying on a mouse. Additionally, the SDK now preserves accessibility information when adding or flattening annotations in documents that already support PDF/UA standards. By automatically inserting the necessary tags, we ensure that assistive technologies can properly interpret document content, helping maintain PDF/UA compliance, and improving compatibility for users with disabilities. ### AI document helpers We’ve added several new features to make working with AI-powered document functionality more straightforward. The SDK now exposes [`NutrientViewer.isAIDocumentComparisonResult`](https://www.nutrient.io/api/web/functions/NutrientViewer.isAIDocumentComparisonResult.html) and [`NutrientViewer.isAIDocumentAnalysisResult`](https://www.nutrient.io/api/web/functions/NutrientViewer.isAIDocumentAnalysisResult.html), along with [`NutrientViewer.AIComparisonPhase`](https://www.nutrient.io/api/web/enums/NutrientViewer.AIComparisonPhase.html). They let you check the type of AI document results and verify the status of AI text comparison operations. These additions give developers more control and insight when integrating AI-driven features into their workflows, making it easier to handle AI-generated insights and comparisons reliably. ### Performance and stability improvements This release includes numerous fixes and enhancements aimed at improving performance and stability across the SDK. We’ve addressed memory leaks when using custom fonts in standalone mode and fixed issues with text selection in multicolumn documents. Various rendering and annotation issues have been resolved, including correct handling of RTL text, Arabic fonts, and dynamic font loading. Other improvements include enhanced support for search functionality, proper rendering of comments and annotations, prevention of crashes when repairing PDFs with missing structures, and better handling of bookmark relocation and outline editing. These changes result in a more robust, reliable experience for developers and end users alike. Minimum Document Engine version required: [1.5.6](https://www.nutrient.io/guides/document-engine/changelog.md#1.5.6) For a complete list of changes, bug fixes, and performance improvements, refer to the [changelog](https://www.nutrient.io/guides/web/changelog.md#1.8.0).
